Well that was quick – but we should probably have the moderators move this to off-topic.
I am building a Prusa Mendel, Iteration 2 – as far as I can tell. Linear bearings.
My printed parts are the cheapest I could find on EBay – and I wish I had spent more. I think they will get me going until I can print my own better replacements.
I am using an Arduino Mega 2560 (I had) with a Ramps 1.4 kit I got from Ultimachine.
SDRamps SD daughter board for disconnected printing.
Heated bed is a Mk 1 off EBay, and it seems great quality.
Hot end is from hotends.com – great price but not here yet.
Running Pronterface to Marlin (Son of Sprinter).
So far I have the frame done and am installing the print bed on the X axis. The motor will be on the back side on mine. Steppers have been tested with Ramps board.
I expect to use my Pi as a local control computer mounted next to the Arduino.
Well this is both off topic and on topic in some ways.
Did you get your linear bearings yet? There are inexpensive ebay/china ones, just not sure how good they are. Haven't found anyone who has a supplier they would recommend, guess I'll have to roll the dice on that one.
I'm going with .9 degree steppers. Heard that they will improve accuracy. I found new ones for a good price $14 each. Going with Sanguinololu electronics again for accuracy as the stepper drivers can do 1/16 increment steps.
I'm also using this 'chain' type stuff for driving x and y. Should minimize or eliminate backlash altogether.
